Oh I meant to explain this.
$messages is built in template_preprocess_page(). You're running in
THEME_preprocess_page() which runs after template_preprocess_page().
$messages is already constructed, so anything you put in dsm() will go
into the $_SESSION variable and show up in the NEXT processing of $messages.
